Pneumatic angle control valve

The angle control valve adopts the top guide structure to realize the adjustment to pressure, flow, temperature and liquid level. It is small size, light weight, low leakage, simple flow route, and low resistance, it can service liquid fluid with high pressure difference / high viscosity / suspended particles. Be convenient to self-cleaning and water cleaning. The angle control valve is generally used in condition of bottom-in & side-out.
